This invention relates to window constructions, particularly useful in motor vehicles, as buses, railway-cars, and the like, and more particularly to double sash windows, wherein there is an air space between the glass panes.

It has for its object a window construction wherein a dehydrating or moisture absorbing ma terial is used to absorb the moisture from the air between the glass panes of the sashes to avoid 1Q clouding, and a construction wherein the dehydrating material is readily removable and replaceable with fresh material. a

It further has for its object a double sash construction, wherein the sash sections abut against each other in air-tight relation, and one of the sections is demountable and provided with a channel opening into the space between the glass panes of the sash sections for receiving a dehydrating material, preferably a granular dehydratlog material, so that when the demountable sash is removed, the dehydrating material may be readily removed from the channel and replaced 2 with fresh material.

It further has for its object the sash construction and the sash and window frame construction hereinafter set forth.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

' -In describing this invention, reference is had to the accompanying drawings in which like characters designatemorresponding parts in all the views.

Figures 1 and 2 are fragmentary front and rear elevations of this'window construction.

Figure 3 is an enlarged sectional view on line 33, Figure l.

Figure 4 is an enlarged fragmentary sectional view of parts seen in Figure 3.

1y different form of the invention.

6 is a fragmentary view, partly in. section, of one of the lower corners of the demountable sash section shown in Figure 5.

usually formed of metal and bf such shape as to form a lining for the window opening in the body of the vehicle, that here 'shownhaving an outwardly extending circumferential flange 2 on the inner side of the frame, that is, the side toward the interior of the vehicle, for lapping the wall of the body around the window opening and forni a facing therefor. The window frame I is also 55 formed with an inwardly extending abutment or Figure -5 is a view similar to Figure 3 of a. slight- I designates the window frame, this being flange d, thisbeing inset from theouter'edse of the frame.

i and 5 are the inner and outer sections of a double sash frame, each of which'carries a glass pane 6 or i which is spaced apart to provide an air space between them. The outer section is formed with a circumferential flange B opposed to one side, of the abutment 3 and with a channel 9 on its inner side, this channel being also open on the side toward the inner section t, The section 5 is also formed with an outwardly extending circumferential flange id opposed to the flange 2 and forming a facing for the margin of the wall around the window" opening The mounting for the glass pane l is located in the channel 9, and this mounting is of a resilient compressible 1na= terlal, as rubber, and includes a channel shaped frame 9; of rubber or other suitable material for receiving the margin of the glass pane i anda backing E2 of rubber extending circumferentially around the frame b and seating in the channel a. It serves to cushion the fixed frame 5 against shocks and relieve the glass pane of undue Strains.

The backing l2 interlocks with the mounting d for the glass pane l, and as here shown, this mounting is formed with a peripheral circumferential groove in which the backing i2 interlooks or seats. The backing l2 isheld from displacement out of the channel 9 on the open side of the channel toward the inner section t by a lip 9 along the inner edge of the bottom of the channel 9' and a shoulder 9 (Figure 4) on the backing i2, which is caught on the lip 9 This construction holds the outer section 5 from unintentional displacement when the inner section t is demounted.

The outer section 5 is secured to the window frame by fastening members, as screws I3 ,extending through the abutment 3 and threading into the flange 8 of the frame section 5, the heads of the screws being located toward the inner side of the window frame or on the same side that similar fastening screws are provided for holding the demountable frame 4 in the window frame,

.so that the screws are accessible when the frame t is demounted. p

The inner frame section 4 is provided with a body flange opposed to and spaced from the abutment 3 and also with a channel M for receiving the margin of the glass pane 6 and a resilient. marginal frame or packing 15. One side iii of the channel I4 is demountable or is a removable glazing strip. M

One of the frame sections, preferably the section 6, is also formed with a spacer rib ll extendchannel.

rib is formed with a channel l8, particularly in the lower rail thereof for receiving a dehydrating or moisture absorbing material. This material is granular and hence can be easily removed and replaced, when the sash frame 4 is removed. The

material used is known commercially as activated alumina.

The frames 4 and 5 are usually formed by an extruding process and the channel l8 for economy in manufacture, is formed throughout the entire extent, with the rib I8, although the channel along the lower rail of the rib is preferably the one utilized for holding the dehydrating material, as no means is necessary for retaining it in the The material used is effective to absorb moisture for aperiod of six months, more or less. The dehydrating qualities of the material are well known.

The inner frame 4,is secured in position and clamped against the resilient backing for the inner glass pane I byfastening members, as screws 20, extending through the inner frame 4 and threading into the abutment 3.

When the-window is provided with a curtain roller, the curtain roller is located inline with or at the level of the upper rail of the sash 4 instead of above the sash frame, so that the curtain roller can be used without requiring extensions of the window frame I in an upward direction, or so that a window frame with a curtain can be mounted in the same window opening as a window frame without a curtain.

22 designates a curtain roller and 23 the curtain thereon, which hasa suitable fixture 24wat its free end for running in curtain guides 25 formed in the uprights of the window frame I. The curtain roller 22 is 'suitably mounted in a box or housing 26 mounted in the .window frame I beneath the upper rail thereof in a horizontal line with the upper rail of the sash section 4.

The top wall of this box or housing abuts squarely against the top rail of the window frame and the end walls 21 thereof are formed with openings for receiving pins 28 on the uprights of the window. frame, the pins snapping into openings in the holes in the end walls. The curtain roller is suitably mounted between the end walls 21..

In Figure 5, a rib' 31 corresponding to the rib H is formed with a channel 38 corresponding to the channel l8 for receiving the dehydrating material; which is packed in the form of a rod or in a perforated tube. The channel is formed with a contracted entrance at 39, and in order that the rod maybe slid into the channel 38, the channel opens at 40 through the bottom of the channel of one of the uprights of the de- 1 mounted section of the sash. The opening at 40 is closed after the rod has been inserted by a plug 4|. Also, in Figure 5, the curtain roller 42 corresponding to the roller 22 is shown as mounte ed in the window frame above the window sash' a hinge plate or strip is provided along the upper rail of the inner sash section 4 and located between said upper rail of the inner sash section 4 and located between said upper rail and the wall 41 of the top rail 41 of the window frame, it interlocking with or hooking over the rib 50 on the w'all.4'l. The two sash sections 4, 5 are secured, in Figure 5, to the abutment 4B, the same as in Figures 3 and 4, except' that the hinge plate 49 is employed in Figure 5. The hinge plate permits the inner sash section 4 to swing open instead of entirely demounting it. 'Itmay be demounted however by lifting it slightly to unhook the strip 49 from the rib 50, after the sash section 4 has been swung outward.

Owing to the construction shown in either Figures 3 or 5, the inner frame 4 can be readily removed by freeing the-screws 20 of the abutment 3 and the dehydrating material removed and replaced with a fresh supply, and when the demountable frame sectionis replaced, tightening of the screws 20 clamps the rib II against 1.
